According to the search results, the thermal conductivity of aluminum silicate fiber paper varies with temperature and product type, as follows:

I. Thermal conductivity range

Normal temperature (20℃): the thermal conductivity is generally 0.03-0.04 w/m k.

At 200℃, the thermal conductivity is about 0.075-0.085 w/m k.

At 400℃, the thermal conductivity is about 0.110-0.121 w/m k.

At 600℃, the thermal conductivity is about 0.160-0.170 W/m k.

At 1000℃, the thermal conductivity is about 0.16-0.17 w/m k.

II. Factors affecting thermal conductivity

Density: The higher the density, the higher the thermal conductivity. When the density exceeds a certain range, the thermal conductivity will gradually increase.

Temperature: The thermal conductivity increases with the increase of temperature.

Content of slag balls: The higher the content of slag balls, the greater the thermal conductivity.

III. Thermal conductivity of different types of aluminum silicate fiber paper

Standard type: the thermal conductivity is 0.075-0.085 W/m k at 200℃ and 0.160-0.170 W/m k at 600℃.

High aluminum type: the thermal conductivity is 0.075-0.085 W/m k at 200℃ and 0.160-0.170 W/m k at 600℃.

Zirconium-containing type: the thermal conductivity is 0.075-0.085 w/m k at 200℃ and 0.160-0.170 w/m k at 600℃.

To sum up, the thermal conductivity of aluminum silicate fiber paper is different at different temperatures and densities, but it has a low thermal conductivity as a whole, making it an efficient thermal insulation material.
